slot_remove(9)

💅 slot_remove(9) — from the Kernel API Manual ✨

okay so bestie, we're in slot_remove(9) territory, from the Kernel API Manual, and honestly? this one is short but she's important. let's get into it 🫶

---

🌸 NAME 🌸

slot_remove — literally removes a node from the linked list of slots. that's it. that's the whole job. iconic behaviour, no notes 💖

---

✨ SYNOPSIS ✨

int slot_remove (struct pci_func *old_slot );

---

🎀 ARGUMENTS 🎀

• old_slot — the slot you want to yeet out of there. it's the slot to remove, bestie, that's the whole vibe 🦋

---

💜 DESCRIPTION 💜

so here's the tea: it returns 0 if everything went fine and slayed, and !0 otherwise. that's the full contract. no cap, that's all the manpage says, and we are not out here inventing extra lore 👑

lowkey a reminder that in C-land, 0 = success and !0 = "something went sideways" — so check your return value, bestie 😭
